A method of catalyzing in vitro reactions using seeds containing enhanced amounts of enzymes is disclosed. The method involves adding transgenic, non-wild type seeds, preferably in a ground form, to a reaction mixture, especially a bakery process and allowing the enzymes in the seeds to increase the rate of reaction. By directly adding the seeds to the reaction mixture the method provides a solution to the expensive and problematic process of extracting and purifying the enzyme. Methods of treatment are also provided whereby a subject lacking a sufficient supply of an enzyme is administered the enzyme in the form of seeds containing enhanced amounts of the enzyme.

Production of enzymes in seeds and their use

Kluyveromyces hosts and DNA expression cassettes for use in Kluyveromyces are provided for transcription of endogenous and/or exogenous DNA, and production of peptides, for enhancing production of an endogenous product, or producing an exogenous product. The Kluyveromyces hosts find particular use for secretion of a desired peptide product, where signal sequences may be native to the peptide or provided from endogenous or exogenous signal sequences, including synthetic sequences, functional in Kluyveromyces. A transformation procedure is provided for efficiently transforming Kluyveromyces.

Kluyveromyces as a host strain

The present invention provides for the expression of phytase in transgenic plants or plant organs and methods for the production of such plants. DNA expression constructs are provided for the transformation of plants with a gene encoding phytase under the control of regulatory sequences which are capable of directing the expression of phytase. These regulatory sequences include sequences capable of directing transcription in plants, either constitutively, or stage and/or tissue specific, depending on the use of the plant or parts thereof. The transgenic plants and plant organs provided by the present invention may be applied to a variety of industrial processes either directly, e.g. in animal feeds or alternatively, the expressed phytase may be extracted and if desired, purified before application.

The present invention provides plants with a modified taste, solids content and/or texture. The invention also provides methods of obtaining such plants via transformation with DNA constructs containing genes encoding enzymes capable of degrading plant polysaccharides and optionally additional genes encoding enzymes which are capable of further modifying the degradation products resulting from the first degradation step.
